Patent number: 10622370Abstract: A method for fabricating a memory device with a self-aligned trap layer and rounded active region corners is disclosed. In the present invention, an STI process is performed before any of the charge-trapping and top-level layers are formed. Immediately after the STI process, the sharp corners of the active regions are exposed. Because these sharp corners are exposed at this time, they are available to be rounded through any number of known rounding techniques. Rounding the corners improves the performance characteristics of the memory device. Subsequent to the rounding process, the charge-trapping structure and other layers can be formed by a self-aligned process.Type: GrantFiled: September 25, 2015Date of Patent: April 14, 2020Assignee: Monterey Research, LLCInventors: Tim Thurgate, Shenqing Fang, Kuo-Tung Chang, Youseok Suh, Meng Ding, Hidehiko Shiraiwa, Amol Ramesh Joshi, Hapreet Sachar, David Matsumoto, Lovejeet Singh, Chih-Yuh Yang
